摘要
文章以花山大桥为例,首先介绍了其概况,随后针对花山大桥的建设条件,展开了其纵向不平衡水平力控制措施的选择及设计,包括控制措施对比、抗推支座设置位置研究及主梁纵向抗推措施设计三方面。以景观因素为主导,选择以墩塔设置纵向限位装置的方式解决不平衡水平力问题,保障了花山大桥受力合理、结构安全,可以为类似桥梁的设计提供参考。
Taking Huashan Bridge as an example,this paper first introduces its general situation;then,according to the construction conditions of Huashan Bridge,the selection and design of the control measures for the longitudinal unbalanced horizontal force are carried out,including the comparison of control measures,the research on the setting position of the anti-thrust bearing and the design of the longitudinal anti-thrust measures of the main girder.Dominated by landscape factors,the problem of unbalanced horizontal force is solved by setting longitudinal restrainer on pier tower,which ensures the reasonable force and structural safety of Huashan Bridge,and can provide reference for the design of similar bridges.
